Censored Truncated Sequential Spectrum Sensing for Cognitive Radio Networks
Censored Truncated Sequential Spectrum Sensing Cognitive Radio Networks
2011/7/6
Reliable spectrum sensing is a key functionality of a cognitive radio network. Cooperative spectrum sensing improves the detection reliability of a cognitive radio system but also increases the system...
Estimation of the relative risk following group sequential procedure based upon the weighted log-rank statistic
Weighted Logrank Statistic Group Sequential Interim Analysis Estimation
2011/3/24
In this paper we consider a group sequentially monitored trial on a survival endpoint, monitored using a weighted log-rank (WLR) statistic with deterministic weight function. We introduce a summary st...
Optimal sequential change-detection for fractional stochastic differential equations
优化序贯Optimal sequential change-detection fractional stochastic differential equations
2011/3/18
The sequential detection of an abrupt and persistent change in the dynamics of an arbitrary continuous-path stochastic process is considered; the optimality of the cumulative sums (CUSUM) test is esta...
